I have a 30 hour musical with dancing figures. when the clock strikes and cuckoos the clock will not stop. There appears to be some sort of release that allows the bird to return home after completing counting the hours.This a rack and snail strike system. Attached to the release lever ther is a bowed arm that should return the bird.can you tell me what settings are required to correctly set this operation..Thank you David

David, in most cases like this the stop pin is missing. There should be a pin in the wheel that drives the fly wheel (the flat regulator). What should happen is the lever drops down when it reaches the bottom of the rack, it moves in front of the pin and the clock stops striking. Look to make sure there is a pin protruding from the second or third wheel from the end of the train. If there is no pin a new pin must be put into the wheel.
